If dark matter has a mass then does a black whole suck in this dark matter and if so then will a large black whole ever evaporate?

Hope he gets a Nobel prize before he dies. He truly deserves it for his great contributions to science.

“How big does a black hole have to be before it doesn’t disappear?”

Black holes will evaporate no matter what their size. Large black holes (millions of solar masses) can’t evaporate right now because the cosmic microwave background gets absorbed by them and is enough to sustain their mass. In the far distant future the cosmic microwave background will be much weaker and won’t be able to sustain the larger black holes.

I can create all of this in a program of viruses based on math and fundamentals. A Universe, a million galaxies at the dial of a mouse. As users of this program we can travel at the speed of whatever we feel. Gravity, magnetism, radiation, atoms, molecules. I can manufacture life that sees itself as real through the program. The animal kingdom and its instinct or the program within a program like I would like to call it could potentially grow like a mirror looking into a mirror for ever. How long could we keep the program running?

Yes, cosmology is in a parlous but interesting state.
90% of mass is missing in galaxies but the ‘universe’ is expanding too rapidly – hence
‘dark energy’.
On negative mass, it seems that if a negative mass and a positive mass were in orbit around each other, they would rotate around a centre with nothing in it!. Hmmmm.
Newton shortly before his death remarked -
‘I do not know what I may appear to the world, but to myself I seem to have only been like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocaen of truth lay all undiscovered before me’.
- oh and by the way hospitals use positrons, ie. anti-electrons, in their PET scanners….

“The use of the letter i for the square root of minus one is due to i being the first letter of the word imaginary. That is because
â€“before the modern definition of complex numbers as ordered pairs of real numbers with a special multiplication and additionâ€“ people thought that the square root of minus one was an “imaginary” number.”

I used to teach mathematics and I think the square root of -1 is not real ie imaginary!!! In fact, try ordering a set of complex numbers and all you get are contradictions! Real numbers can be ordered and no logical contradictions are created.

If I am not correct, please correct me.
Thanks.

Forget about black holes. Like all things black they can be sidelined or marginalized or reduced or starved out of existence by A-Holes that spend hundreds of billion on pathetic experiments to satisfy some craving for fame and to prove that their fantasies are right.

There are only two holes of any concern. The A-Hole and the Pink Hole. A-Holes do not get enough Pink Hole and get frustrated and contract, retaining toxic waste. This fogs the brain which becomes delusional and is unable to create an event horizon around the pink hole. The pink hole , now starved of charm retreats into a singularity and devours all that crosses it’s path. A-Holes, in an effort to reduce this ferocious suction, feed the Pink Hole mega tonnes of bullshit to expand the event horizon so they have a better chance of getting some. The more complicated the bullshit the tastier it is for the pink hole which oozes in appreciation and takes on the new spin and jumps to a brand new energy level. This in turn excited the A-Hole in new and unexplored territory where entire languages are invented to further excite the Pink Hole.

Now it hasn’t happened yet but one day the event horizon will expand to include the A-Hole in the Pink Hole territory and an explosion only measurable in Schwarzschild/Hawking cumletmefucku units will occur, obliterating all traces of the A-Hole and the Pink Hole, and sadly the poor old black holes.

Ahhh nature – so unforgiving!
